网上有类似的错误日志，有两种说法：1,：客户端主动断开连接导致报错；2：jetty版本bug，试了两种方案后问题没有解决：

我的解决方法是：提升karaf jvm 内存

Apache Karaf accepts environment variables:JAVA_MIN_MEM: minimum memory for the JVM (default is 128M).JAVA_MAX_MEM: maximum memory for the JVM (default is 512M).JAVA_PERM_MEM: minimum perm memory for the JVM (default is JVM default value).JAVA_MAX_PERM_MEM: maximum perm memory for the JVM (default is JVM default value).KARAF_HOME: the location of your Apache Karaf installation (default is found depending where you launch the startup script).KARAF_BASE: the location of your Apache Karaf base (default is KARAF_HOME).KARAF_DATA: the location of your Apache Karaf data folder (default is KARAF_BASE/data).KARAF_ETC: the location of your Apache Karaf etc folder (default is KARAF_BASE/etc).KARAF_OPTS: extra arguments passed to the Java command line (default is null).KARAF_DEBUG: if 'true', enable the debug mode (default is null). If debug mode is enabled, Karaf starts a JDWP socket on port 5005. You can plug your IDE to define breakpoints, and run step by step.You can define these environment variablesin bin/setenv Unix script (bin\setenv.bat on Windows).For instance, to set the minimum andmaximum memory size for the JVM, you can define the following values:On Unix:# Content of bin/setenvexport JAVA_MIN_MEM=256Mexport JAVA_MAX_MEM=1024MOn Windows:rem Content of bin\setenv.batset JAVA_MIN_MEM=256Mset JAVA_MAX_MEM=1024M

根据指导，该配置为

export JAVA_MIN_MEM=1024M  # Minimum memory for the JVM

export JAVA_MAX_MEM=2048M  # Maximum memory for the JVM

问题得到解决
